In 1947 Mr. José Gavira, the Librarian, published his catalogue and he talked about an interesting deposit with over 5000 titles ranging over different subjects and not reduced to Geography. Since then, the library has grown although its pilgrimage in search for a final location has resulted in irrecoverable losses, such as those suffered from the fire that happened when the RSG library was located at 10, Magdalena street in Madrid.

Fortunately, these problems were solved with the agreement reached with the Biblioteca Nacional in relation to the deposit of our funds in its premises. Since 1971, our Library is deposited in the adequate place and available to every body.

In his catalogue, Gavira made an excellent classification that is fully valid nowadays and enables looking for any works as well as understanding the relevance of the copies and of their authors. Subjects range from bibliography to philosophy, to religion, sociology, the army, economy, sciences or technology, to jurisprudence or mathematics, apart from Geography in all its branches: general, descriptive, human, travels and explorations, and mapping.

Logically in a Society founded in the last third of the 19th century, the printing date of most publications is from that time or later. There are, however, some books from the 16th, 17th and 18th centuries, presented by members to the Library.
